<?php
 
 
// Function: Insert From Vals
// Take an associative array and build an insert statement
//
// $table -> the table you want to fill
// $prefix -> the prefix of the fields ( ie, auto_color -> 'auto_' )
// $vals -> the array to insert, default _POST
//
// Please note that this will work with normal database naming and not with 
// special names with spaces and accents and odd stuff
//

function insertFromVals( $table , $prefix , $vals = null )
{
	$fields = array();
	$vallues = array();
